My sander works fine. I have put on a few belts and used some blending bar and felt and some 400-600 grit. My first job is to sharpen about 20 knives, some real good steel and stainless some not. None of them need to remove much metal if any. I have 180, 280, 400, and 600 grit belts. I have a few felt belts and both a blending and a polishing bar. Know that I have this stuff I thought I would ask the Pro's what logical steps to follow and about how long or how many times to do each. After I turned 50 I realized what a great idea it is to ask questions before you ruin a lot of things during the learning process. Am I to avoid that wax stuff covering the blending bar? Please assume I know nothing because as far as this equipment and process I don't. Thanks Buckfever
